Ecotec Z22YH in 2003 Opels.
US experience started in earnest in 2006 with the LNF turbo four and in 2007 with the LLT 3.6L V6 in the CTS, and since then it's spread like a virus across GM's product line.

Well, Bubba considers 4 cylinders half an engine and 6 cylinders 3/4th of an engine anyway, so that dog wouldn't hunt down here.

So I was on Hennessey's website and he lists future upgrades to he 2014 ATS-V with TT V6. Think he knows something we don't know.

That has nothing to do with direct injection.

GM will have to deal with Bubba as well as Eurosnobs to market the car.

The pistons are relatively small compared to the cylinders so slight weight addition to the piston is more than offset by the large reduction in cylinder wall weight. Remember the Aurora L47 4.0 Northstar? The smaller bore increased the weight enough that they had to design a lightweight manifold and simplify the fuel injection system to compensate, so the weight gain must have been significant.
